What
Claude Code had a separate step for reapplying a changed settings file. It first ran your ConfigChange hooks, and if none of them blocked it, it reloaded the settings. A hook is a command you set up for Claude Code to run automatically at certain moments, and ConfigChange hooks run when a configuration file changes during a session. That reapply step has been removed. So has the message saying a ConfigChange hook blocked reapplying.
Why
If you use ConfigChange hooks to vet settings reloads, they may no longer be asked before a changed settings file is reapplied this way.
